So, I have had a vague idea for a murder mystery one shot amongst a high class Elendel dinner for awhile. The players could be various individuals either of the same house (but different standings), various nobility, or wealthy merchants (or family members of them). A wealthy lord descended from the lord mistborn himself is having an overnight social to decide where to invest some of their assets. Only for him to not appear at dinner and be mysteriously murdered. Basically want my players to play detective and hopefully learn more about the magic systems (Alas I have yet to convince them to really get into the cosmere).
Thoughts, advice, etc? Any comments are welcome to those who feel inclined to share. Thank you in advance for engaging with the topic.
